?lm coil container into the other against the

aperture surface at the rear end of the camera
era.”
My present invention relates to photographic UK body when the magazine is brought into opera
tive picture-taking position with the ?lm coil con
cameras and more particularly to photographic

Another object of my present invention consists
in combining the ?lm magazine with the camera
body in such a manner as to use all available
space within the camera body for useful purposes,
thereby substantially reducing the size of the
camera.
With the above objects in view, my present
invention mainly consists of a photographic cam

focal plane of the camera lens normal to the opti

A removable ?lm magazine of new type also

This new ?lm magazine comprises two ?lm coil
containers being spaced from each other; one
of these containers houses the unexposed and
the other the exposed ?lm coil. These ?lm coil

is secured to and forms part of this ?lm exposing
member and is arranged in the space between the
?lm coil containers and secured to the magazine,
and near the front end of the same and being
open at the rear. The top and bottom plates
completing the camera body are secured to ‘the
top and bottom faces of this body and extend

I might provide on the outer face of the front
wall of the camera body additional wall-like pro
jections extending from the upper to the lower
edge of the front wall parallel to each other and
to the side walls of the camera body. These ad
ditional projections are arranged on the front
wall at both sides of the camera body, forming
together with this front wall an open channel
shaped space. The two plates forming the top
and bottom of the camera body and being secured
to the top and bottom faces of this body extend
from the front edges of these additional wall—
like projections to at least the rear end of the
camera body, thus forming together with the
front wall of the camera body and the additional

picture-taking position but without the shutter
mechanism.
An important part of my new camera is the
camera body shown in Figs. 1 to 6. This camera
body consists of a central body 20 containing the
exposure chamber 25 and the camera lens 22.
As clearly shown in Fig. 4, the camera body 20
has a rectangular cross section and is bounded
by the two side faces 23 and 24, by the top face
25 and the bottom face 26. The front wall 21
of the camera body is wider than the camera
wall-like projections on this front wall a com
body itself and extends in direction of the side
partment for the camera shutter mechanism.
Simultaneously, these top and bottom plates form
faces 23 and 24 over the same, as shown in Fig. l.
The end portions 23 of this front wall 2'! are bent

faces 23 and 2d of the camera body 20 and front
wall El substantially semi~oylindrical compart
As mentioned above, the camera body may con
tain a compartment for the exposure chamber
and for the camera lens. However, it should be
stressed that it is not necessary and not part of
my present invention that the camera lens is ar
ranged within the camera body and that it is
also possible to arrange the camera lens and the
mount therefor as a more or less separate unit
on the front face of the camera body, for instance
in front of the shutter mechanism.
I also wish to stress that usually the magazine
will be housed by the compartments described
above without any additional cover closing the
rear of the camera body. However, if desired, it
is also possible to provide such a separate cover
and to enclose the entire ?lm magazine into the
camera.
The novel features which I consider charac
teristic of my invention are set forth in particu
lar in the appended claims. The invention
itself, however, both as to its construction and
its method of operation, together with additional
objects and advantages thereof, will be best un
derstood from the following description of spe
cl?c embodiments when read in connection with
the accompanying drawings in which:
Figure 1 is a top view of my new camera body
with the top plate shown in dotted lines;
Figure 2 is a side view of the camera body
shown in Fig. 1;
Figure 3 is a front view of the same camera
body;
Figure 4 is a rear view of the same camera
body;
Figure 5 is a top view of one of the plates to
be secured to and forming part of the camera
body shown in Figs. 1 to 4;
Figure 6 is a side View of the plate shown in
ments 29.
The camera body is furthermore provided with
various recesses 3i! and Si serving for accommo
dating the diaphragm adjusting means and
other mechanisms of the camera. Thus, through
recess 39 a film transporting member 44, which
will be described below more in detail, extends
from the front face 32 of the camera body to its
rear face 33 serving as exposure surface, engag
ing the film strip moving along this rear face.
The top and bottom of my new camera are
formed by the top and bottom plates 34 shown
in Figs. 5 and 6. These plates are substantially
larger than the top and bottom faces 25 and 26
of the camera body 20; thus, they project over
the edges of these faces when they are secured
to the same by screws 35 and locating pins 36.
In order to show clearly the relative position
and relative size of the camera body itself and
the cover plates 34, the top plate is shown also
in Fig. 1 in dotted lines. As may be seen, this
cover plate extends from front wall 21 and the
rearwards projecting portions 28 of this wall to
the rear face of the camera body 29, thereby
forming the compartments 29 on both sides of
the camera body Bil, as shown in Fig. 14. These
compartments 29 serve for housing the film coil
containers of a ?lm magazine.
Furthermore, the front portions 31 of the top
and bottom walls 34 form together with front wall
